resize "/ " under LVM 2005-10-05 - By Greg Hosler

<disclaimer>I haven't used RHEL3 since about U4+</disclaimer>
RHEL3 did not have ext2online resize command, and required volumes to be
offline to be resized. You then used e2fsadm (as I recall) to resize both
the volumn as well as the partition.
in your case, you shouldn't need to make a new volume, just add more space
to the original volume.
The tricky part will be resizing the lv, though.
I can't think of any way to do this from a mounted running system.
Several ideas which do pop into mind follow (none are that elegant though):
- boot into rescue mode (from disc1: linux rescue), and see if
e2fsadm is on the disc, and if it iss, try that. Not sure if
that will work, or not. If the rescue cd will recognize your
lvm when it mounts your file systems, then you _might_ be ok.
- install a simple install onto a spare disk, on a spare machine.
borrow your root disks/volumes from your main system, plug them in
as secondary disks on the new system, and do the extension there.
(I can think of all kinds of problems you might encounter, none of
them pleasant, but it *might* work.)
needless to say, before any of the above, you really want to backup your system.
on the other hand, the installer can do this, so it probably should work (and
since the installer can do this, it _should_ work from a rescue cd, since that's
the base set of utilities that the installer happens to use :)
lvm on RHEL3 and lvm on RHEL4 are 2 different animals. From what I undserstand,
they come from completely different code bases. I would probably not expect
ext2online from lvm2 (rhel4) to work on rhel3. I do not recall if there was
work going on on ext2online for lvm1 (rhel3) or not.
best rgds (and best wishes!),
